| 摘 要： | 以三峡库区大宁河流域为例,提出了基于流域属性和模型敏感性参数两种相似流域的识别方法。案例研究结果表明,基于参数敏感性法的相似流域识别结果较好,评价标准等级划分精细程度会影响属性法的结果。当评价标准很精细时,两种相似流域识别方法得到的结果趋于一致,表明两种方法均可用于相似流域判定。同时,两种方法各有其适应性,在实际应用时可将两种方法相结合,以便获得更为精确的识别结果。本研究所提出的方法有助于改善农业非点源污染模拟技术,实现农业非点源污染影响的准确量化。

| Abstract: | Identifying similar basins in ungauged catchments is a foundation of agricultural non-point source pollution simulation.Using Daning watershed as a case study,two methods were proposed to identify similar basins based on attribute and parameter sensitivity.The results indicated that the method to identify similar basins based on parameter sensitivity performed well.The precise degree of evaluation criteria levels has an impact on the result of attribute method.When the evaluation criterion levels are particularly precise,the identified results of the two methods tend to be consistent.Thus both the two methods could identify similar basins.However,the two methods have different applicability.In practical applications,combining the two methods would obtain more accurate results.The methods proposed in this paper will be of great importance in improving agricultural non-point source pollution simulation techniques and quantifying the impact of non-point source pollution. |
